TAP Foa BEER, sac.

SPECIFICATION forming part of Letters'Patent No. 248,262, datedOctoloer11, 1881` To all lwhom it may concern Be it known that I, JOHN F.PAULFRANZ,

a subject of Bavaria, Germany, residing in the whichof the plug.

Figure 1 is a side elevation of the cap of the tap embodying myinvention. Figs. 2 and G are end views thereof. Fig-3 is a side viewFig. 4 is an end view thereof'.

Fig. 5 is a longitudinal section of the complete device.

Similar letters ot' reference indicate corresponding parts in theseveral figures.

My invention consists of a plug to be attached to the barrel, keg,'&c.,and containing a valve, a cap to be secured to the plug provided withmeans for causing the proper register of the parts and expansion ofpacking, and a cock adapted to open the valve of the plug provided withmeans for attachment to the cap.

Referring to the drawings, A represents a tubular plug, which iseXteriorly of cylindrical, conical, or other suitable form, and adaptedto be inserted in the tap-hole of a barrel, keg, Sto., containing beeror other liquid, said plug having an opening, a, for the passage of theliquid from the keg. Within the plug is fitted a sliding valve, B, whichis held closed, covering the opening a by means of a spring, C, whichbears against the plug and valve, as shown in Fig. 5'. The head b of theplug has formed on its circumference spiral grooves D, and in its frontend one or more openings, c, and the surface of the plug adjacent to thehead may be threaded for screwing the plug to the keg in the tap-hole,as above referred to.

E represents a cap consisting of a shell, d, which is adaptedto encirclethe head b of the plug, and containing a tubular block, F, from whoseinner face project studs or pins e, which are adapted to enter theopenings c ot' the head of the plug A. The outer or forward face of lthe block F has a tubular extension, Ef, which Application tiled July13, 1881. (Model.)

H represents handles, which are secured to the cap E for the purposeofrotating the same; and J represents studs or pins projecting inwardlyfrom the shell of the cap, adapted to enter the spiral grooves D of theplug A, each stud and. handle in the present casel being formed of' onepiece ot" metal.

K represents` packing of suitable material, placed against thc block Fon the side opposite to the extension E', the pins e passing through thepacking,land the center of the latter being perforated for the passageofthe shank or inlet-branch ot' the cock G, the packing, when the partsare in position, abutting against. the front end ot' the head ot' theplug A. The cock G is ot ordinary construction excepting the attachmentof thespring catches or fastenings F', and has at its inlet end anopening, a', which is adapted to register with the opening a ot' theplug A.

L represents a washer, which is titted on and secured to the extension Eof the block F,and

-abuts against the front walLf, of the cap E,

the latter thus being held in position by the washer L and block F onopposite sides ofthe front walhf, of said cap.

M represents a pin, which is secured to the rotary cap E,'and projectshorizontally forward from the front wa-lLf, thereof. A portion of thecircumference of the washer L is cut away, as at 7L,the ends oftheportion forming shoulders k, which limit the motion of the pin M, thelocation and play of the latter being in said cut-away portion It.

The operation is as follows: When the plug A is in position,the valve B,pressed outwardly by the spring C, closes the opening a and preventsescape of the liquid from the keg. When the keg is to be tapped the capE is fitted to the head b of the plugA. For this purpose said cap isrotated either by the handles H or the pin M until the pin strikeseither of the shoulders h of the washer L. This places the studs J andpins e in such positions that they register, respectivel y,with thespiral grooves D and the openingcof the head of the plug. Then press thecap to full extent over the head of the plug and rotate it, wherebyit isscrewed to and wedged tightly on the head of the plug. As the packing Kis pierced by the pins e it is prevented frorn being turned and therebyinjured,

IOO

but being pressed by the block F against the head ofthe plug,itiscompressed and expanded, thusformingatightjointbetween thecap, plug, andblock, and also bears tightly around the inlet branch ofthe cock whenthe latter is applied,thus preventingleakagebetween'the plug and cock.The cock is now forced through the bore ofthe extension E', block E, andplug A, thus pressing back the valve B and uncovering the opening aofthe plug, and causing said opening to register with the opening tt' ofthe inlet branch of the cock. When the catches F of the cock reach thenotches or shoulders g of the extension E they engage with them, so thatthe cock is irinly connected to the cap, and all the parts are held inoperative position. It is now evident that the beer, &c., may be drawnsilnplyby properly turning the plug ofthe cock. By operating vthefastenings F so that they leave the notches or shoulders g, the cock,under action ofthe spring-pressed valve B, leaves the cap and plug, ormay be withdrawn there Jfrom,the valve B immediately closing andcovering the opening a. The cap is then rotated so that the studs J arereleased from the spiral grooves D of the plug, and thus the cap andplug are separated. The plug may be removed or remain a fixture ofthekeg, Src.

The valve B is of the forno of a -hollow cylinder, so as to receive thespring C, by which construction I ain enabled to use a shoot-valve andspring, and inclose the latter.r Access is had to the valve and springby means of the screw-cap A', which forms the end ofthe plug opposite tothe head b thereof, one end ofthe spring abutting against said cap.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

1. The plug A, having an opening, a', and 4o a head,b, with spiralgrooves D, and the rotary cap E, with studs J, combined and operatingsubstantially as and for the purpose set forth.

2. The rotary cap, E, the tubular block F, with extension i', and theplug A, combined and operating substantially as and for the purpose setforth.

3. The rotary cap E,with studs J, tubular block F, with pins c, the plugA, with spiral grooves D and openings c, and the washer K., combined andoperating substantially as and for the purpose set forth.

4. The rotary cap E and plug A,in combination with the pin M and theshouldered'washer L, substantially as an d for the purpose set forth.

5. The plug A and rotary cap E, in combination with the block F, formedwith a tubular extension, E', and the washer L, said cap encircling thebloclqand the washer being tixed to the extension, the washer and blockbeing on opposite sides of the front wall ofthe cap, substantially asand for the purpose set forth.

6. The plug A and cock G, in combination with the valve B and spring C,said valve being of hollow cylindrical form, inclosing the spring,substantially as and for the purpose set forth.

7. The plug A, the block F, the tubular extension E', having shouldersg, andthe cock G, havingcatchesF,combinedandoperatingsub- 70 stantiallyas and for the purpose set forth.
